In this paper, wire electrical discharge machining of D3 tool steel is studied. Influence of pulse-on time, pulse-off time, peak current and wire speed are investigated for MRR, dimensional deviation, gap current and machining time, during intricate machining of D3 tool steel. Taguchi method is used for single characteristics optimization and to optimize all four process parameters simultaneous...

Tłumaczenie to aktywność, w trakcie której, podobnie jak procesie interpretacji jej konkretnego efektu postaci tekstu docelowego, ze szczególną wagą ujawniają się odniesienia do różnych kontekstów źródłowych i docelowych. Na tym tle pouczająca może być analiza rozmaitych przypadków lepszego lub mniej przekonującego dostosowania docelowego rzeczywistości jego odbioru. Proponowane studium przypad...

The optimization of parameters considering multiple performance characteristics of the EDM process for SS 304 using the GRA is presented. Performance characteristics including MRR, TWR, and OC are chosen to evaluate the machining effects. Those process parameters that are closely correlated with the selected performance characteristics in this study are the pulse-on time, current, and voltage. ...

This article proposes a hybrid algorithm for spectrum allocation in cognitive radio networks based on the algorithms Analytical Hierarchical Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to improve the performance of the spectrum mobility of secondary users in cognitive radio networks. To calculate the level of performance of the proposed algorithm...

Sulfonated carbon nanotubes (S-CNTs) and sulfonated graphene (S-Gra) with superior dispersibility were successfully prepared to modify poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) for applications in polymer solar cells (PSCs). The synergetic effect between S-CNTs/S-Gra and PEDOT:PSS could remove excess insulating PSS chains leading to an obvious phase separation between ...

Glucosinolates (GL) can inhibit, retard or reverse experimental multistage carcinogenesis. When brassica plant tissue is broken, GLs are hydrolyzed by the endogenous enzyme myrosinase (Myr), releasing many products including isothiocyanates (ITC). Synthetic ITCs like sulforaphane exert chemopreventive effects against chemically induced tumors in animals, modulating enzymes required for carcinog...
